Removing Cats

[Zackpn]

Removing cats on manifold will it bring engine light on?

Is it worth running the last cat on a sports cat?

if so how can i not let them on.

cheers

Well the two cats on the manifold are going anyway due to turbo down pipe. but dont want engine light on.

Removing the cats on the manifold will not bring the EML on. Those cats are known as Precats and a lot of members who have theirs supercharged will remove them as they break up under high temperature and clog the main cat. Easy job is to cut open a flap, gut it and weld the flap closed.

All I know about a sports cat as the main cat is that anyone who I know who has fitted one it has failed and had to be replaced. That's two people and it's enough to put me off fitting one.

That is like the best ever answer I have had on any car forum top lad! :)

Thanks

I know im a bit late to this thread but Zack did you get a decat manifold in the end or just gut it?

Did you have any problems?

Removing the cats will make it sound raspy , won't give you any gains , leave them in mate not worth the hassle .

Some people remove the cats when fitting a supercharger because they say it runs much hotter and destroys the cats .

It doesn't anyway but like I say don't waste your time .
